Hydraulic stimulation strategies in enhanced geothermal systems (EGS): a review
Geomechanics and Geophysics for Geo-Energy and Geo-Resources, 2022 AbstractIn enhanced geothermal systems (EGS), the natural permeability of deep rocks is normally not high enough and needs to be increased. Permeability increase can be achieved through various stimulation methods, such as hydraulic, chemical, and thermal stimulation.
